METHOD OF MANUFACTURING PACKAGE MATERIAL.

SPECIFICATION forming part of Letters Patent No. 653,323, dated July 10,1900*.

Application filed November 13, 1899. Serial No. 736,744. (No specimens.)

To ctZZ whom t may con/cern.:

Be it known that I, WILLIAM S. STUoKuN- BERG, a citizen of the UnitedStates, residing in Indianapolis, in the county of Marion and State ofIndiana, have invented a new and useful Improvement in Methods ofManufacturing Package Material, of which the following is aspecification. t

Fabrics for the manufacture of open or ventilated shipping crates andpackages have been heretofore made consisting of a series of parallelseparated slats with transverse binder-wires stapled to the slats anduniting them together, and such a fabric is shown in the patent toGreenstre'et, No. 547,486, and a machine for attaching the slats to thewires is shown in the patent to the same inventor, No. 579,574.

My invention relates to the method of manu facture of fabrics of thisclass, although it was more specially devised for the manufacture of afabric in which the slats were secured to binders made of band-iron bymeans of tongues integralwith the bands and punched from them and thendriven through the slats and clenched.' The slats used in these fabricshave heretofore been cut from what is known as veneer stock-that is tosay, stock about one-fourth inch or less in thickness-and they have beenso cut while the sheet of veneer was yet hot and moist from the log. Inmy invention instead of rst severing the sheet-veneer into slats, as hasheretofore been the practice, I take a sheet of freshly-cut Veneerhaving sufficient width to form all the slats required in a sin` glepiece of the fabric and as the first operation secure the binders,whether the same are Wire or band-iron, transversely across one face ofthe sheet, using fasteners such as have been heretofore employed forattaching the severed slats to the binders and locating the fastenersprecisely as they have been located heretofore-that is to say, so theywill serve to attach the individual slats into which the sheet issubsequently converted properly to the binders. I thenV score or nearlysever the sheet upon the face thereof opposite to that to which thebinders are applied along equidistaut lines and between thebinder-fasten ings, thereby, in effect, dividingthe sheet into slats,but without wholly severing them from each other. The sheet thus scoredand attached to the binders is now allowed to dry and the shrinkagewhich then occurs cornpletes the separation of the slats along the linesat which the sheet had been scored, and thereby forms theVentilating-spaces required in the fabric. This scoring may be easilyand quickly done by machinery, and it will be noticed that my inventionsaves the handling of the individual slats.

The accompanying drawings show at Figure l a perspective of the sheet ofveneer from which a section of the fabric is produced. Fig. 2 is aninside View of the same after the binders have been applied thereto.Fig. 3 shows the same after scoring. Fig. 4 is an edge view of thescored sheet; and Fig. 5 is a similar view of the scored sheet afterdrying, the latter view being partly in section.

Referring to the drawings, 6 represents the wet unscored sheet ofveneer, and 7 7 the binders, of which there may be any number desired.The bindershere shown are of bandiron and the sheet is attached theretoby tongues 8 8, punched out of the binders and forced through the sheetand clenched, as clearly illustrated at Fig. 5. The scoring is shown at9 9 and passes nearly through the sheet, but does not eect a completeseveration, the completing of the severation being effected by theshrinkage, as already eX- plained.

I claim- The method of manufacturing package material from green or wetWood sheets, consisting in applying thereto transverse metal binders andattaching such binders to the sheet at intervals'correspondin g to thewidth of the desired slats, then scoring the sheet between thefastenings, and then allowing the sheet to dry, whereby the shrinkagecompletes the severation along the lines of the scoring and converts thesheet into separated and spaced slats, substantially as specified.
